DIRT-SHIELD FOR PICKS.

To all whom t may concern.' Be it known that I, AMIL Moonen, a .citizenof the United States, residing at Willis* ton, in the county ofWilliams, State of North Dakota, have invented a new and usefulDirt-Shield for Picks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates to a dirt shield for picks, and has forits object-to provide a device of this character which embodies novelfeatures of construction whereby it can be readily applied to the handleof a pick or like tool and will prevent hard particles from flying intothe face and also prevent mud from being spattered upon the clothes.

Further objects of the invention are to provide an adjustable shield forpicks which is comparatively simple and inexpensive in its construction,which can be readily applied to a pick or removed therefrom, which canbe adjusted to fit different sizes of picks, and which will enable thepick to be used upon hard surfaces such as paved streets without thedanger and discomfort which is occasioned by the flying of solidparticles into the face.

"With these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in whic Figure 1 is aside elevation of a conventional pick showing a dirt shield constructedin accordance with the invention applied thereto.

Fig. 2 is an end elevation of the pick taken on the line 2 2 of Fig. l.

Fig. 3 is an enlarged side elevation of the dirt shield, the pick handlebeing shown in section.

Fig. 4 is an enlarged transverse vertical sectional view through thedirt shield.

Fig. 5 is a horizontal sectional view through the same taken on the line5--5 of Fig. 3.

Corresponding and like parts are referred to in the followingdescription and indi- Speccaton of Letters Patent. Patented Allg.14,1917. Application filed May 31, 1917.

cated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral l designates a handle of anordinary pick 2 of the type which is commonly used for digging upon thestreets. The shield includes a split sleeve 3 of sheet metal or likematerial, said sleeve carrying a guard plate 4 which is rigidly securedthereto and normally projects downwardly therefrom. The edges of thesplit sleeve 3 overlap each other at the top of the handle 1, and may beslotted to receive a tubular bolt 5. .A nut 6 is threaded upon thetubular bolt and it will be obvious that the size of the sleeve 3 can beadjusted to t any particular handle by causing the edges thereof tooverlap more or less, and the sleeve then locked in an adjusted positionby tightening the nut 6. A set screw 7 is threaded within the tubularbolt 5 and provides a means for locking the sleeve 3 in an adjustedposition upon the handle l.

The guard plate 4 projects downwardly from the sleeve 3, and is shown ashaving an extension S adjustably fitted upon the lower end thereof,thereby enabling the guard plate to be lengthened or shortened, as maybe found necessary to obtain the best results. The sides of theextension 8 may be returned around the edges of the guard plate 4, asindicated at 8a, and suitable fastening means such as the screws 9 maybe provided for locking the extension in an adjusted position.

When the pick is being used in soft earth the dirt shield can becompletely removed therefrom, since under such conditions it would notbe desirable to have the shield upon the pick. However, when the pick isto be used for digging in hard material,

'as upon a paved street, the sleeve 3 is slipped over the pick handle 1,having been previously expanded or contracted to fit the pick handlewith a fair degree of accuracy. i4fter the sleeve has been properlypositioned upon the pick handle the set screw 7 is tightened, therebylocking it securely in the desired position. The extension 8 can then bemoved in or out to vary the effective size of the guard plate, and whenthe pick is used the flying particles of stone and mud which wouldotherwise strike against the person of the user will be intercepted bythe guard plate.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is

l. In combination with a piek, a split sleeve adapted to be iitted uponthe piek handle, means for adjustably connecting the Aedges of the splitsleeve for varying the siZe thereof, means for looking the sleeve in anadjusted position upon the piek handle, and a transverse guard platerigid with the sleeve and projecting downwardly therefrom.

2. In combination with a pick, a split sleeve adapted to be litted uponthe piek handle and formed with slotted overlapping edges, -a tubularbolt adjustably connecting ltheslotted overlapping edges, a clamping,nut threaded upon the tubular bolt, a set vscrew ,j extending throughthe tubular bolt 'for engagementwith the handle to look the sleeve .inan adjusted position thereon, and a transversely disposed guard platerigid -with thesleeve and projecting downwardly therefrom.

3. In -eomblnation with a piek, a guard plate disposed transversely withrespect to Vthe piek handle and projecting downwardly `with the sleeveand projecting downwardly therefrom, an extension adj ustably mountedupon the bottom of the guard plate, and inea-ns for looking theextension in an adj usted position.

ln testimony whereof l have signed my name to this speeilication in thepresence or 40 two subscribing witnesses.
